The WATERCLOUD_NOTIFY Log Gave Hackers 4,841 Working Logins

What the WATERCLOUD_NOTIFY Stealer Log Exposed This Time

HEROIC analysts tracked another WATERCLOUD_NOTIFY stealer log, this one uploaded by a Telegram user on 18-Jul-2024. The file holds 4,841 records, pairing email addresses with plaintext passwords and the URLs each login belonged to.

Why This Is Dangerous

Stealer logs hand attackers something far more dangerous than a random password list, they hand over credentials that were actively in use on a real device at the moment of infection. With 4,841 confirmed working logins in one file, an attacker has a large, ready-made toolkit for breaking into accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

A file this size gives criminals enough volume to run large-scale credential stuffing campaigns, testing each email and password pair against banks, email providers, and shopping sites. Any password reused across accounts becomes an open door for account takeover, identity theft, or financial fraud.

How This Stealer Log Works

Stealer malware spreads through cracked software, fake downloads, and malicious links, then silently harvests saved passwords and browser data from every infected machine. The WATERCLOUD_NOTIFY operation appears to package these hauls into labeled files like this one, complete with URLs and passwords, ready to be shared or sold.

Check If You Are Affected

The only way to know for sure is to check. HEROIC's free breach scanner compares your email against more than 400 billion leaked records, including this WATERCLOUD_NOTIFY log, so you can act fast if your information turns up.
